Dundalk's European adventure is on the line tomorrow night against Slovan Bratislava and head coach Vinny Perth has called on his team to throw caution to the wind as they seek at least one goal in Tallaght.

The Lilywhites trail 1-0 from the first leg of their Europa League third round qualifier and know they must breach the Slovakian defence if they are to progress to a play-off for the group stages.

A battling display last week looked enough to bring a goalless draw back to Ireland, but David Holman's late goal secured the Slovakian champions a narrow win at the Tehelne Pole Stadium.

John Mountney’s header was clawed onto the crossbar at the death, but Perth knows his team must up the ante in the attacking third.

"We have to be a little braver than we were last week, but at the same time, their goalkeeper made three outstanding saves on the night and we did go after goals," he told RTÉ Sport’s Tony O’Donoghue.

"Our attacking threat was there, but we can create more opportunities in the final third and that is the challenge we have set the players.

"We have given them that licence to be a little braver."

The domestic champions have understandably found the going tougher in Europe with just one goal in their last seven outings.

"We are operating at the highest level and it's not easy," Perth explained, who is expecting strong support on the night as the Irish club look to advance.

The Lilywhites will make the not unfamiliar journey to the capital for their latest European tie and with the game not screened on TV, Perth is calling on football supporters across the board to come out.

"The stadium is a credit to Shamrock Rovers and it is a tremendous setting for a European tie. We have had some great nights in Tallaght and the bigger pitch generally suits us.

"We need to create an atmosphere. There has been a lot of doom-and-gloom around Irish football. For us to grow as a league, we need to be putting our name out the in Europe. Not just Dundalk, but League of Ireland.

"I think it is a night where football fans should come out and support each other."

Perth must once again plan without midfielder Robbie Benson (above) after the 27-year-old shipped a heavy bang to the ribs against Qarabag in the Champions League qualifying defeat. He is close to a return, but won’t be rushed back to face the Slovaks.

The head coach has revealed that Benson has addressed the squad ahead of the crunch fixture.

"Robbie has asked us that we get one more European tie. He has asked us to win as he wants to play in Europe again before the season is out.

"We will do our best."
